Rose Pink

: ON THE PRIMARY, RED.

Is a coarse kind of lake, produced by dyeing chalk or whitening with

decoction of Brazil wood, peachwood, sapan, bar, camwood, &c. It is a

pigment much used by paper-stainers, and in the commonest distemper

painting, &c., but is too perishable to merit the attention of the

artist.



Chevreul obtained a crystalline substance from Brazil wood, which he

looked upon as the pure colouring matter, or as containing the pure

colouring matter, and which gave red and crimson precipitates with many

salts. Possibly some of these might prove more durable than the roughly

made rose pink.
